摘要： 基于测试和信号定义(STD)标准给出的形式化定义，对自动测试系统(ATS)软件平台进行静态与动态建模。通过绘制类图的方式明确接口之间的关系，改进STD中的信号状态转换图，设计该软件平台的时序关系。实验结果表明，该平台通过信号组件之间的Sync接口与Gate接口可灵活、准确地实现信号触发与同步功能。

Abstract: Based on formalized definition of Signal and Test Definition(STD) standard, static and dynamic model for Automatic Test System(ATS) software platform is built. The relationship among interfaces is demonstrated while drawing the class diagram, the signal state change diagram is improved, the running sequence of the platform is designed. Experimental results show that this platform can realize the function of signal synchronization and trigger through Sync and Gate interface between signal modules.

Key words: Signal and Test Definition(STD), Automatic Test System(ATS), modeling
